FirmFax prop firm data is a remote MCP server that gives an AI agent 6 tools, among them compare_firms, find_firms, get_evidence. It answers at https://firmfax.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Independent rule and fee data on 71 prop trading firms, every figure with its evidence state.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
compare_firms | Two firms side by side. Reports each figure with its evidence state and whether the pair is comparable at all: a field neither firm records is not a tie, and a field only one records is not a win. No per-field winner is declared, because th Inputs: a, b |
find_firms | Firms matching every criterion given. A firm whose record does not carry a criterion is never counted as a match and never silently dropped: it is returned separately under unknown, with the field that could not be tested. Absence is common Inputs: assetClass, maxActivationFee, maxResetFee, maxConsistencyPct, maxDailyLossLimit, maxMinTradingDays |
get_evidence | The stored reading behind a figure: the verbatim quote, the page it came from, and the date we read it. Answers "we hold none" explicitly rather than returning an empty list. `outcome` is load-bearing: a `contradicted`, `contradiction` or ` Inputs: slug, field |
get_firm | One prop trading firm. Every figure states whether we hold evidence for it, and a firm whose score range spans more than one band carries no letter grade at all. Inputs: slug |
get_rule_changes | The dated record of what changed, newest first. Every entry states its KIND, and most of this tape is FirmFax correcting its own data rather than a firm changing its rules. Read counts before describing industry activity: a total taken acro Inputs: slug, since, kind, limit |
list_firms | Every firm slug and name. Carries no figures, so nothing here needs evidence. |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://firmfax.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
